Abstract (en)

[origin: WO2007124942A1] Disclosed is a circuit arrangement comprising a first and a second microcontroller, the second microcontroller being connected to the first one. The inventive circuit arrangement has the following characteristics: - the first microcontroller is configured such that a main process which controls or regulates at least one output signal of the first microcontroller as well as a safety process that is embodied so as to recognize a faulty state of the first microcontroller can be executed in parallel; and - the second microcontroller is configured as a watchdog such that a signal that overrules the output signal of the first microcontroller can be output when the safety process recognizes a faulty state and/or when the second microcontroller recognizes a faulty state on the second microcontroller. The invention further relates to a method for operating a circuit arrangement.
